I have been looking everywhere for an owners manual for this preamplifier for weeks with no luck! Tried faxing Spectral but no reply. Anyone out there know where I could download or I would pay good money for an original manual! Please contact me if you have one or know of one. Thanks!

I had the the support department for Spectral Audio on the phone today and I took the liberty to mention your request for fax or digitized copy of the MS-One owners manual. The very nice gentleman replied that they have only hard-copy versions of the owners manuals on hand, with the exception of the oldest models. The MS-One Preamp is one of the first units that they produced, and they unfortunately had no more copies available.

Thank you very much for your help! I will keep posting on as many audio sites as I can to try to find one. I know the MS-one was the original flagship of Spectral back in the mid 70's. Damian Martin was the genius behind the MS-One. He had posted on a web site that there were only 15 to 20 of these ever put in production.
